Do you know when you visit a web site, you behavior might be monitored and tracked? If I tell you that there are six sites will be monitoring you when you visit MSNBC web site (www.msnbc.com), will you believe it?
Thanks to a nice browser plugin called Ghostery, you can find all those hidden sites that are tracking you. I highly recommend everyone to download and install it, and the plugin is available for Internet Explorer, FireFox, Google Chrome, and Safari.
Note: lots of web sites are using Google Analytics to track web site visits, so if you use Ghostery and enable tracking block, you need to remember to uncheck Google Analytics from the the blocking list.
Here is a screen shot displaying all web sites that are tracking you on MSNBC web site.
